Scotland, with its soft, acidic waters and old, lead‐plumbed dwellings, is acknowledged to have a serious problem with plumbosolvency (dissolved lead). Recent medical studies have confirmed that unacceptably elevated concentrations of lead in blood correlate with excessive levels of lead in drinking water. Bottle‐fed infants were shown to be particularly at risk. But controlled water treatment that reduced lead solubility by pH adjustment and phosphate addition was found to be an effective method of reducing concentrations of lead both in water and in blood.
